Test Environment: W7 pro 64; 3.6ghz CPU; FF 3.5.12; 8400x4200 equirect.
I think the corner folding bug is fixed. I could not find a trace of it in two different equirects. Good job!
Also, mouse wheel scrolling seems smoother than before - which is good.
I have the Visuals settings at 84 fps and quality high (12) with very good response and little to no tearing. Very nice!
I like Scaling with No Border -- it is very smooth and the kind of window resizing response that I like.
I noticed one little detail. If I create a swf file with Scaling: With Window the cursor image is smaller than if I create a swf file with Scaling: (No Border; Exact Fit). Odd but not a show stopper.
Also, I notice that I no longer have to check the Invert check box to get the mouse wheel to zoom "normally" when I am outputing Flash (swf). But I have to check the Invert check box to get the mouse wheel to zoom normally when I am outputing HTML5/CSS3.
This is the limit of my testing......
